The problem most people have is how to keep their hair color vibrant  longer. Its all in how you treat your hair. When having colored hair its always  recomended to use a salon color safe shampoo and conditioner. It is well worth it if you want your color to last. Unlike drug store brands it is free from sulfate which actually drys out the color in your hair which cause your hair to fade. Also try to avoid exposure to sunlight, pools, and hot tubes. Try to wear a hat in the sun when you can or use a conditioner which protects against uv rays.  The uv rays can dry out your hair and cause it to fade. The chlorine in swimming pools and hot tubs can also cause your hair to fade. Use a uv protecting coditioner in pools as well, or tie hair up.
